Many human social phenomena, such as cooperation, the growth of settlements, traffic dynamics and pedestrian movement, appear to be accessible to mathematical descriptions that invoke self-organization. Here we develop a model of pedestrian motion to explore the evolution of trails in urban green spaces such as parks. Our aim is to address such questions as what the topological structures of these trail systems are, and whether optimal path systems can be predicted for urban planning. We use an… 

Self-Organizing Pedestrian Movement

The dynamics of pedestrian crowds is surprisingly predictable and the corresponding computer simulations are a valuable tool for developing optimized pedestrian facilities and way systems.

Self-organization and optimization of pedestrian and vehicle traffic in urban environments

Self-organization is not only a feature of urban evolution, but also found within urban environments. Here, we will focus on three aspects: (i) spatiotemporal patterns in pedestrian flows and their

Self-organized trail systems in groups of humans

An experimental platform for studying the trail systems that spontaneously emerge when people are motivated to take advantage of the trails left by others is developed and the results are compared to the Active Walker model of pedestrian motion from biophysics.

Realistic human walking paths

This work presents a novel behavioral model of path planning that extends previous models through its significant use of pedestrian performance statistics that were obtained during a suite of experiments, and develops an original interpretation of quantitative metrics for measuring a model's accuracy.

Lévy walk process in self-organization of pedestrian crowds

It is found that before (but not after) lane formation, pedestrians deviate from the desired direction by Lévy walk process, which is considered optimal when searching unpredictably distributed resources.

Looking for Human Footprint in Nature : Collaborative Mapping for Monitoring of Self-organized Patterns in Human Trail Systems

A web-based multimedia GIS system was employed to handle Volunteered Geographic Information that were produced by the participants in the different multimedia formats as well as the temporal images and videos that were acquired by the UAV system in centralized approach.

Analyzing trails in complex networks.

The results show that the topology of the network influences trail reconstruction, source identification, and agent dynamics, including the Internet, the U.S. airlines network, an email network, and the scientific collaboration network of complex network researchers.



Modelling urban growth patterns

CITIES grow in a way that might be expected to resemble the growth of two-dimensional aggregates of particles, and this has led to recent attempts1á¤-3 to model urban growth using ideas from the

It is suggested that the motion of pedestrians can be described as if they would be subject to ``social forces.'' These ``forces'' are not directly exerted by the pedestrians' personal environment,

A Two-Fluid Approach to Town Traffic

A two-fluid model of town traffic has been developed by extending ideas formulated in an earlier kinetic theory of multilane traffic to consist of moving cars and cars stopped as a result of traffic conditions, and contains a new parameter identified with the quality of the traffic network system.

Generic modelling of cooperative growth patterns in bacterial colonies

It is shown that a simple model of bacterial growth can reproduce the salient features of the observed growth patterns, and incorporates random walkers, representing aggregates of bacteria, which move in response to gradients in nutrient concentration and communicate with each other by means of chemotactic 'feedback.

Sexual Differences in Human Crowd Motion

The hypothesis that males and females behaved as though they belonged to different populations in an otherwise homogeneous crowd was hypotheses that were not anticipated during the planning of the observations and the data on the differences between the sexes were not complete enough to test the hypothesis.

The Further Evolution of Cooperation

Empirical andoretical work has led to a deeper understanding of the role of other factors in the evolution of cooperation: the number of players, the range of possible choices, variation in the payoff structure, noise, the shadow of the future, population dynamics, and population structure.
